SPECIFICATION forming part of Letters Patent No. 552,074, dated December24, 1895.

Application filed. July 5, 1895. $erial No. 564,947. (No model.)

To aZZ whom it may concern.-

Be it known that I, VIRGIL G. RICHEY, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Cultivators; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

My invention relates to improvements in garden-cultivators, the severalfeatures of which will be fully hereinafter described and claimed.

The object of my invention is the construction of a cultivator whichwill be readily adjustable laterally to suit rows of varying widths, andalso adjustable as to the depth the hoe may penetrate the soil.

The mechanism is illustrated in the accompanying drawings, in whichFigure 1 is a side elevation of the implement. Fig. 2 is a plan of thesame with some parts omitted. Fig. 3 is an enlarged detail plan of thehandle part.

Like letters and numerals designate like parts in all the views.

The wooden handles A are of the usual form and are connected to thespindles O by the supporting arms L. These arms are bolted to the sidesof the handles and have orifices, into which are fitted said spindles.The handles at their outer ends are connected by two cross-bars 10 and11 and the diagonal braces 8 and 9. The outer ends of said diagonalbraces are bolted to the under sides of the handles, and the inner endsare bolted to the cross-bar 10, which has slots 12 in the ends, andwhich construction admits .of the adjustment which is effected by theaxle D. This axle comprises two bars, the lower ends being bent underand rigidly bolted to said supporting-arms. They extend vertically asuitable distance, bent at a right angle and terminate in loops,whichembrace each other, and the pin 13,which passes through the two partsand bind the same. To effect the lateral adjustment of the hoes theseparts slide upon each other and are bound by the pin,

as before specified. The two arms E are in the form of an obtuse angle,and at the points of their angles are provided orifices, which embracethe spindles and upon which these arms freely move. In their lower endsare held within orifices the round bars I and on the inner ends of whichareheld the hoes G. The top ends of these arms are notched or an orificemay be provided, into which is placed the stirrups if, only one of whichis shown in the drawings, the ends of which are rigidly fastened to theplate 1, which is loosely held on the rod F. To this rod is fixedlyattached the plate 2, and between said plates the two spiral springs 3bear. In bearings on the cross-piece 11 is held the rod H, and to thisrod are rigidly attached the arms J, and the rods F connect these armswith the pivotal arms E. The arm 5 is attached to the outer end of saidrod, and to thisis attached the locking-plate 4, which is pressed downby the fiat spring 6, and the pin of which engages the notched plate 7,which is attached to the handle, and by this means the hoes are adjustedas to the depth of penetration of the soil.

The usual form of cultivator-hoe G or any other form, if provided withan orifice, may be secured to the rod I by a set-screw, which enters acountersink of said rod, (not shown in the drawings,) and the same issecured to the arm E in the same manner to prevent any rotation. Theaxle is adjustable to fix the position of the ground-wheels, the handleslikewise to accommodate the former adjustment, and the hoes are readilyadjusted laterally-to suit the rows of plants by moving the hoes alongthe sustaining-rod.

In operating the implement it is simply pushed along over the rows ofvegetation to stir the soil after the several adjustments are made, asthe circumstances may require. The depth of penetration is regulated bythe lever or arm 5, as the farther it is drawn back the deeper thepenetration.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. In a garden cultivator the combination of the handles A, the wheelsG, the supporting arms L, the adjustable axle D secured to said arms,the spindles O, the pivotal arms E, 'the stirrup tWith its plate, therod F with its plate, the spiral springs 3 between said plates, the rodsI, held in said pivotal arms, the hoes G held on said rod, the arm 5with its engaging-plate 4C, and the notched plate 7 attached to thehandle, substantially as described.

2. In a garden cultivator the combination of the pivotal handles A, theadjustable frame D, the ground Wheels 0, the arms E held" on
